IMPROVED MACHINE vFOR MAKING SHEET-METAL PANS.

Specification forming part of Letters Patent No. 59,104, dated-October 23, 1866.

To alt whom it may concern:

Be it known that I, ORVILL W. VAY, of the city of Troy, in the county of Rensselaer and State of New York, have invented a new and Improved Machine for Making Rectangular Pans of Iron or Tin 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being hereby had to the accompanying drawings, which make and form a part of this specification.

Like letters represent and refer to like or corresponding parts.

Figure l is a perspective View of my said machine as it would appear when not in use, showing the various parts thereof', each .more fully hereinafter described and set forth. Fig. 2 is also a perspective, showing the platform or inner dieC, pressed downward and the adjustable dies or wings B in a perpendicular l position, as they would appear when in the act of forming a pan, substantially as hereinafter described and set forth. Fig. 3 is a cross-section, showing the platform or inner die, @,and

the coiled spring E, which supports and holds the same, also the outer adjustable die or win g, B,and the means by which it is fastened to the table or body of the machine, each more fully hereinafter described and set forth. Fig. 4 shows a pan, F, surrounding the die Gr, which shapes the form and size of the pan to be made, also 'showing the handle or projection H, to which the motive power is applied inthemanner and means substantially as hereinafter described and set forth. Fig. 5 is a view showing a pan as it would appear when nished by my said machine, also showing the flanges U, which are hammered down in the manner hereinafter describedand set forth.

The nature of my said invention and improvement consists in the employment of four adjustable wings or dies, B, in combination with the inner die or platform, (l, by which means pans of tin, sheet-iron, or other metal can be made better and with greater rapidity than has heretofore been the case.

It also consists in so constructing the said outer dies or wings, B, and the said inner die or platform, C, as to be movable or adjustable, so that rectangular pansof any size or dimension can be made in the same machine, substantially as hereinafter described and set forth. A

It also consists in so constructing the said platform or inner die, C, as to work or operate the dies or wings B in the manner and for the purposes hereinafter described.

To enable others skilled in the art to which my invention relates to make and use the same, I will here proceed to describe the construction and operation thereof, which are as follows, to wit:

The various parts of my said machine are made fast to a table or any level surface, A, by any means deemedbest which will be of sufficient strength and answer the desired purpose. The platform G, upon which the die Gr rests when making a pan, has an arm or colj umn, L, projecting down and through the said table or level surface A, and has a coiled spring, E, surrounding the same. The said columuL passes through a suitable cross-bar, K, and has a nut and screw, J, on the under side, which keeps it in its proper place when the machine is not in operation. The said spring E may be of anymaterial and strength required, according to the strength of the material which is to be made into pans.

The platform C and arm or column L may be made of any metal or wood deemed best; but I generally prefer to have the platform C, as well as the dies B and G, made of iron, as it is best adapted for that purpose. Y

The dies or wings B are fastened to upward projections M on the slides N, Figs. l-. and 2, by means of rivets ruiming through the said upward projections M and through the downwardv projections O on the said adjustable dies or wings B.

The slides N are made of wood or any other material deemed best, andhare fastened to the table or level surface A by means of screws, as seen at Figs. l and 2.

I)Figs. l, 2, and 3, are oblong pieces of any material deemed best, which are screwed onto the slides N, and which are for the purpose of regulating the distance that the said dies or Wings B should be pushed downward when the saidmaehiue is in operation making pans, accordin g to the bevel desired to give the sides of the pans so making.

All of the said slides N and oblong pieces or bevel-regulators? are adjustable, and may be regulated so as to make any size pan de sired by means of the screws working in the slots R, as seen in Figs. l and 2.

D, Figs. l, 2, and 3, are springs, which are fastened at one end to the slides N, and at the other to the upper end of the said dies or wings B, so that when the same are pressed down in the act of making a pan there will be enough resistance by the said dies B to bend the tin 0r iron, thereby forming the pan, substantially as hereinafter described and set forth.

The strength of the said spring will bc regulated according to the flexibility of the material from which the pan is to be made. The shape, size, style, and strength of the said dies or win gs B,as Well as the platform or inner die, G, may be such as will best answer the purpose required and suit the style and strength of the pan to be made; but the said dies or wings B must extend under the said platform C far enough so that when the platform C is pressed downward the dies B will be pressed into a perpendicular position, substantially as and for the purposes hereinafter described and set forth.

The said slides N workin recesses formed by means of two pieces, S S, Figs. l and 2, which are fastened onto the body or level surface of the machine by any suitable means, and are for the purpose of holding the said slides always in the same place and at right angles with each other, which is an essential feature in the successful manufacture of pans.

G, Fig. 4, is the die around which the pan is made, substantially as hereinafter described,

while F, Figs. 4 and 5, shows the pan as it would appear when finished by my said machine.

T T, Figs. l and 2, are right-angle pieces, made of any material deemed best, which are fastened to the body of the machine, substan tially as seen at Figs. l and 2, and are for the purpose of guiding the tin or sheet-iron to its proper place on top of the said dies previous to forming the same into a pan. The said right-angular pieces work backward and forward by means of a slot and screw, the same as the slides N, and for the same purpose-viz., to regulate them according to the size and shape of the pan to be made.

f Vhen it is desired to use my said machine for the purpose of making pans the mode of operation is as follows: The tin or sheet-iron is cut into pieces of the requisite size. The piece to be made into a pan is then placed upon the dies B and platform C and pushed forward until it touches the upright regulators T T, which have previously been adjusted to the size of pan to be made, as also have the Vvarious dies. The die G is then placed upon the tin or sheet-iron, and directly over the platform C. Suitable motive power is then applied to the shaft H on the said die G, and as the platform C descends the said dies or wings B catch upon the under side of the same, and are pressed downward until they strike against the oblong projections P. The tin or sheet-iron is, of course, bent to coliform with the shape of the dies B and G. There is a space between the corners of the said dies B for the flanges U, which will necessarily be made upon the pan thus formed. The die G is then raised, allowing the said dies or wings B to spring back to their first position. The par. F will then be seen formed around the die G, as seen at Fig. 4 in the accompanying drawings. The flanges U are then hammered down by hand in any suitable manner.

When it is desired to change or adjust the dies of my said machine for the purpose of making pans of a different size, the platform or die C is loosened and removed by means of the screw V and one of the size desired placed in its stead. The dies B are also removed and ones of corresponding size with the pans to be made put in their place, and-are regulated to the proper distance by means of the screws working in the slots R of the slides N. The manner of proceeding is then the same as heretofore described.

Having thus described the nature of my said invention and improvements, what I claim as my invention, and desire to secure by Letters Patent of the United States, is-

l. The employment and arrangement of the movable and adjustable dies or wings B, in combination with a central and verticallymoving platform-die, C, in the manner substantially as herein described and set forth.

2. The employment of the downward-moving platform or die O as the means for working or operating the said dies or wings B, in the manner and for the purposes substantially as herein described and set forth.

3. The said dies or wings B, in combination with the slides N and the bevel-regulators P, in the manner and for the purposes substantially as herein described and set forth.

In testimony whereof I have, on this 20th day of February, 1866, hereunto set my hand.
